I have this scale form an article (unfortunately doesnt say what they did to make all items into one scale) its composed of 6 questions 4 multiple choice and 2 yes/no. How do i put these together to make a new variable because they are all part of the same construct. FOr example the multiple choice questions are 1. How much info about a product do you share with your friends? a. alot b. average. a little ? So 4 questions are like this and the other 2 are yes/no. How do I make one constrcut item from these in spss? Greatly appreciate your help!
